i've been having alot of contrations and braxton hicks contractions this is my fourth pregnancy, i'v emade this far , I 've had 5 other pregnancies, but had misscarraiges with them and i can't really tell if its real labor pains or not, but it starts from the top and wraps around my back, i've been feeling extra weak and very irritated and restless, i hardly sleep, i've told my doc but it's like wasting my time, do i have anything to worry about if i have high risk of preterms and misscarraiges in the past(yes my doc knows this)???
